i 'lhis invention relates to." punching and has for an object tofprovide 2in-improved construction whiclifmay be readily jinoved from placevto place while continually in con#` dition foruse.`v` f i y*Another object of the invention is =to yprovidea punchingbag wherein the bag` portion .is connected with means for yieldingly main` Y taining the bag' in a' certain position.

" A further objectof the invention isf-to provide' a'punching'bag in which the bag structure is carried by the base structure i capable of being shifted from place to place without interfering with the proper movementof the bag. y l

.A still further object,` morehspecitically, isf to provideV a punching vbag wherein a weighted ball is provided at the'base `for r normally maintainingthe `bagin a ygiven i returning the bag `to said Vgiven position f when moved therefrom.l Y l -v In the accompanying drawings-v position and for automaticallyand quickly Figure 1 is a perspective viewof a/punching bag disclosing a .preferredembodimenty ofthe invention. e l .y

Referring to the acoompanyingdifawings by numerals, 1 indicates the bag section and 2 the base while 3 indicates a rod or connecting member for connecting the bag section 1 to the base 2'. The base 2, as shown more particularly in Figure 2, includes al ball 4. a support-ingdisk or plate 5 and a bodyy 6. The body 6 is formed with a ring 7 and av yplurality of supporting legs 3, each of said legs'having a foot 9 projecting through a suitable notchin the ring 7. These legs are riveted or votherwise secured to the ring 7 Y `and also are .riveted or otherwise secured to the plate 5. 1 The Vplate 5'is provided with a suitable Aball race in which anti-friction balls 1() are mounted, saidballs being'posiand a hollow upper section 12p -rThe' tioned to engage and support theball 4. The

ball 4 is provided with a solid. lower section uppersection 12 anannular .proj"eating y sleeve 13 adapted to press-against the shoulder 14 ofrod VK25-when a threaded section l'15,.'

is screwed into asocket 16." y When -.-'the threaded section 15 is screwedirmly in place as showninFigure 2, shoulder-14 vwillgpress i in tightly against the sleeve 13 whereby there will be some little tension between thefparts. It will also benoted from Figure 2 thatthe anti-frictionballs 10 are positionedfslightly below the" center e or; equatorfof the ball .4

whereby the weighted section l1 will continue to lioldrod -3 land associated parts in y 2 a` vertical position. `YVhenthis rod has been moved out offthe .verticalfandthen released,

At the r extreme upper Y end of the rod 3y is provided av plate 17 havinga` socket y18 in lthe weighted or solidjsection 11 will quickly v nieve the parts back toal Vertical`position. f

which the/end'of rod ,3 is'litted, said end be-V y v t ing held in. the socket `by suitable screws19. V l

apertures for yaccommodating thevlacling` whereby the canvas or otherfabric, casing21 Plate 18 is also provided with ,a number of f ofbag 1 isproperly held injposition. At*- the bottom of bagl isgarrangedsaplate similar to plate `l except that it has an aplerture or bore v extending entirely therethrough.` The plate is also4 provided with a tubular portion l8conneoted withthe rod 3 by suitable screws 19.` Lacing '20l passes through suitable'apertures inplat-e 17` and `i i through the fabric casing21 for holding the lower end of the bag 1 in proper position;

Arranged .within the fabric Vcasing 2l is `a I rubber bag or bladder 22 which may be .of

any desired thickness and rwhich `is provided l i with a tube 23 securedat its' ends to the respective ends of thev bag'or loladder22.-l

` This hagor bladder22 is shown 'inorefin l detail in Figures 2 and 4'.' An air inlet 24 of any desired kind is provided, vsaid air ine let being adapted to 4be folded andtied asy vshown in Figure 5' after a desiredv pressure of airy has been providedin lthe bladder. Thek casing 21v is provided with yanopening 25 which is normally heldgtogetherby lacs ing 26 when the bag is in use.` In order to take care of unusualy strain at the topand bottom, the bladder 22 1s' provided with reinforcing .plates or sheets 27 and 28 ,of rub- .i ber which are cementedor otherwise firmly secured to the end ofthe bladder 22; v y f The'feet 9 at the base are preferably aps ertured so that whenthe device is placed von the lolorrgata given point it maybe irmly anchored by somel screws passing through the feet 9, though for light use, the 'weight of the base will be suiiicient to hold the device in operative position. Preferably, the diameter of the bag lv is greater than the diameter of the base so that in case theA bag lv should be struck and forced over until it hits the floor, rod 3 would not strile" the plate 5. When an action of this kind takes place, .Y the solid section 11 immediatelyl ingV- sai'dball.

2. A punching bag including a pneumatic bag structure, a rod for supporting the bag structure, a ball connected to the lower end of said rod, saidy ball comprising a solid Asection forming substantially halt1 the ball and a hollow section forming the other half oi" the ball, a rod extending through the holl'oW section into the solid section, anda base engaging the ball near the equator for rotatably supporting said ball.

3. In a punching bag a counterbalancing ball comprising a hollow section and a solid section, a base'for rotatably supporting-,said

ball formed With a supportingplatel having a round aperture therein through which said ball projects for almost hal-ii' its diameter, and anti-friction means carried by said plate positioned` to engage the ball near its equator for supporting the same on said plate.

4; ni a punching bag a base, af rockable counterbalance supporting member carried by the base', rod carried by said rockable supporting member, and a pneumatic bag carried by the'A upper end vol" said rod, said rod having enlarged sections engaging the ends of said for holding the bag in position on the rod. v

5. In a punching bag supporting` means including a rod and a bag mounted on said rod, said bag including an inner 'rubber bladder, a reinforcing rubber end member connected to each endo' said bladder, and a 'fabric covering near said bladder, said bladder being orm'edwith an Ainlet valve structure and said covering mei'nber being formed with an opening-through Which said valve may project when the bladder is being inflated, andfastening means `for normally holding said opening closed.`

6; ln a punching bagy a support including a rod, ay bag mounted onthe upper end ot said rod, said bag' comprising a bladder hayingl a tube extending therethrough 'ron'i one end to the other adapted to be telescoped over said rod, a fabric casing surrounding said bladder,- and means for securing said fabric casing to'l said rod'.
